Determine the physical origin of enhanced TM-EoS variability

Determine the physical driver of the enhanced 86 GHz and 230 GHz flux variability produced by the temperature-dependent TM equation of state relative to the constant-adiabatic-index equations of state, using dedicated time-lag analyses of horizon magnetic flux, accretion rate, and thermodynamic averages.

Background

The simulations find that the temperature-dependent TM equation of state produces substantially larger flux variability than the constant-$\gamma$ models at both 86 GHz and 230 GHz, consistently across the considered electron-heating prescriptions and electron distribution functions. The paper does not identify the causal mechanism behind this enhancement and indicates that resolving it would require time-dependent diagnostics correlating variability with horizon magnetic flux, accretion, and thermodynamic evolution.
